Items starting with S

Salvage

An intermediate cutting made to remove trees that are dead or in imminent danger of being killed by injurious agents.

Sanitation

An intermediate cutting made to remove dead, damaged or susceptible trees to prevent the spread of pests or pathogens.

Sanitation Salvage

In range management, a site allowed to be overgrazed to obtain efficient overall use of the management area. In cultural resource management, it may refer to a site intentionally sacrificed to extensive public use in order to preserve the larger cultural area.

Sapling

A loose term for a young tree more than a few feet tall and an inch or so in diameter that is typically growing vigorously.

Scale

Refers to the geographic area and data resolution under examination in an assessment or planning effort. In ecosystem management, it refers to the degree of resolution at which ecosystems are observed and measured.

Scenarios

Predictions of future events and outcomes based on techniques of decision science. Scenarios are often expressed as 'risk profiles', charts or tables that display the probability of an outcome occurring and its consequences.

Scheduled timber harvest

The quantity of timber planned for sale during a specified time period from the area of suitable land covered by a land management plan. Scheduled timber harvest accomplishes the allowable sale quantity.

Scoping

Scoping determines the "scope" of the subsequent environmental analysis conducted by an interdisciplinary team of resource specialists. Scoping is an ongoing process to determine public opinion, receive comments and suggestions, and determine issues during the environmental analysis process. It may involve public meetings, telephone conversations, or letters. The ongoing process to determine public opinion, receive comments and suggestions, and determine issues during the environmental analysis process. It may involve public meetings, telephone conversations, or letters.

Second Growth

Forest growth that was established after some kind of interference with the previous forest crop, such as cutting, fire, or insect attack.

Sediment (sedimentation)

Solid materials, both mineral and organic, in suspension or transported by water, gravity, ice, or air; may be moved and deposited away from their original position and eventually will settle to the bottom.

Seed tree cutting

The cutting of all trees except for a small number of widely dispersed trees retained for seed production and to produce a new age class in a fully exposed microenvironment. Seed trees may or may not be removed after regeneration becomes established.

Seismic Exploration

Seismic exploration remains the most common way to locate sub-surface resources. The process involves sending sound waves into the earth at one point and recording them at others after having passed through differing geological strata. There are two common methods utilized today. One method involves the detonation of small explosive charges. The other method consists of a truck that drops a huge weight at various intervals. The data collected is used to show probable sub-surface resource deposits.

Selective cutting

A cutting method that removes only a portion of trees in a stand.
